我们可以使用Java代码来获取Badssl.com的证书链，然后与在浏览器中获得的证书链进行比较。这将有助于确定服务器是否在返回不同的证书链。

以下是Java代码示例：

import java.io.IOException;
import java.security.cert.Certificate;
import java.security.cert.CertificateEncodingException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import java.util.ArrayList;
import java.util.List;

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLPeerUnverifiedException;
import javax.net.ssl.SSLSession;
import javax.net.ssl.SSLSocket;
import javax.net.ssl.SSLSocketFactory;

public class CertificateUtils {

    public static void main(String[] args) {
        compareCertificateChains("https://badssl.com/");
    }

    public static void compareCertificateChains(String url) {
        List javaChain = getCertificateChain(url);
        List browserChain = getCertificateChainViaBrowser(url);

        if (javaChain.equals(browserChain)) {
            System.out.println("The certificate chain is the same when accessed via Java and browser.");
        } else {
            System.out.println("The certificate chain is different when accessed via Java and browser.");
        }
    }

    public static List getCertificateChain(String url) {
        List certChain = new ArrayList<>();
        try {
            HttpsURLConnection conn = (HttpsURLConnection) new java.net.URL(url).openConnection();
            conn.connect();

            SSLSession session = conn.getSSLSession();
            Certificate[] certs = session.getPeerCertificates();

            for (Certificate cert : certs) {
                if (cert instanceof X509Certificate) {
                    certChain.add(getCertificateFingerprint((X509Certificate) cert));
                }
            }
            conn.disconnect();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return certChain;
    }

    public static List getCertificateChainViaBrowser(String url) {
        List certChain = new ArrayList<>();
        try (SSLSocket socket = (SSLSocket) SSLSocketFactory.getDefault().createSocket()) {
            socket.connect(new java
